Title: Recent progress in the phenomenology of tensor currents in QCD

Abstract: I will report on recent developments in the phenomenological 
aspects of spin-1 tensor currents in QCD. In particular, I will concentrate 
on 3 of the most prominent quantities that can be studied, namely the 
1^{+-} b1(1234) meson, the magnetic susceptibility of the quark condensate, 
which is relevant in interactions of nucleons with external electromagnetic 
fields, and the couplings of the tensor current to 1^{--} vector mesons, 
currently under intense study by lattice groups in order to improve the 
determination of the CKM matrix element V_{ub} extracted from exclusive 
B decays.
